Answer:
A. Unit rate.
Step-by-step explanation:
We have been given a statement and we are supposed to choose the correct option for our given statement.
Statement:
A constant of proportionality can also be considered a(n) .
Since we know that constant of proportionality represents the amount by which two proportional quantities vary.
Two quantities are directly proportional, when they are in form , where k represents the constant of proportionality.
We can represent this proportion also as:
Since k represents the quotient of y and x, so the value of k represents the unit rate for two quantities y and x, therefore, a constant of proportionality can also be considered an unit rate.

The answer is 1.
4x + 3x - 1 = 6
7x - 1 = 6 -Add the like terms
7x - 1 + 1 = 6 + 1 -Add 1 to both sides to 7x by itself
7x = 7
7x / 7 = 7 / 7 -Divide both sides by 7
x = 1
Hope I helped!
To put this into words, the equation is saying that one less than 4x + 3x is equal to 6.
First simplify by combining like terms. We see there is a 4x and 3x, which means that they are compatible with each other. The equation will then look like . If one less than 7x is 6, then this can also mean one more than 6 is equal to 7x. So add 1 to both sides:
--> , which means that x = 1.
Checking your work:
Now that we know the value of x, substitute that for x in the equation like this:
-->
--->
So you know it's true that x = 1. Hope this was helpful.

Jess needs 3/4 cup of sugar. Note that 3/4 is the same as 1/4 + 1/4 + 1/4, which in turn is the same as 3(1/4).
Jess will need to fill her 1/4-cup measure 3 times to end up with 3/4 cup of sugar in the banana bread batter.

Multiply x and 1
The x just gets copied along.
The answer is x
x
0.75*x evaluates to 0.75x
Because of the minus sign
0.75x becomes - 0.75x
The answer is -0.75x
-0.75*x+6 evaluates to -0.75x+6
Multiply x and 2.5

2.5*x evaluates to 2.5x
2.5*x-1.9 evaluates to 2.5x-1.9
To subtract the polynomials -0.75x+6 and 2.5x-1.9 we try to subtract terms in one polynomialwith any like terms in the other polynomial.
Be very careful with the "-" sign in front of 2.5x-1.9 it is to be used on all terms in it.
-0.75x - 2.5x = -3.25x
6 - -1.9 = 7.9
The answer is -3.25x+7.9
(-0.75*x+6)-(2.5*x-1.9) evaluates to -3.25x+7.9
